conronn- COIN CONTROLLED SWITCH AND TIMING MECHANISM Application filedJanuary 14, 1932. Serial No 586,498.

This invention relates to improvement-sin time and coin controlledmechanism for controlling the actuation of a switch device used inconnection with electric circuits, where it is desired to automaticallyactuate a switch device at the expiration af a predetermined time limit,for renderingthe circuit active or inactive as the case may be, and oneof the objects of the invention is to provide improved mechanismassociated with a clock work, whereby upon the insertion of a propercoin or token the switchmechanism will be actuated after the expirationof aipredetermined time limit, for controlling the circuit, and improvedmeans whereby in the absence of a proper coin or token, the switchmechanism will be maintained against operation while the operation ofthe clock work will not be interfered with.

A further object is to means for manually setting the switch device uponthe insertion or presence of a proper coin or token, and improved meanswhereby the switch device will be locked or prevented from beingmanually actuated in the absence of a proper coin or token. f

A further object is to provide an improved connection between the clockwork and a check carrier of the coin controlled mechanism, embodying afriction clutch, and improved means whereby said friction clutch will beautomatically rendered inactive in the absence of a proper coin or tokento permit the clock work to operate independently with respect to thecheck rier will be prevented from operation. 7

To the attainment of these ends and the accomplishment of other new anduseful objects as will appear, the invention consists in the features ofnovelty in substantially tlie construction, combination and. arrangementof the several parts hereinafter more fully described and claimed andshown in the accompanying drawings illustrating this invention and inwhich V Figure 1 is a front elevation of a device of this characterconstructed in accordance with the principles of this invent-ion.

Figure 9 is a detail view in sect-ion of the frictioirclutcli showingthe clutch member expanded.

Figure 10 is a detail view showing the movable member of the check chuteand a portion of the check carrier.

Referring more particularly to the drawings the numeral 15 designates asuitable supporting p'late upon which the mechanism mounted and thisplate together with the mechanism suppo' ted thereby is adapted to beencased in a'suitable casing not shown, and-.in which casingthere' isprovided an opening through which the dial'16 constitutcheck "carrier,showing a check in and the position the parts will asing the face of theclock work, is visible.

The clock face or dial 16 1s secured to the plate15 in any suitablemanner and is preferably spaced therefrom by means of elements 17 toform aspace 18,.and in which sp ace is arranged a gear wheel 19 which issecuredto a main shaft 20 of a clock work mechanism designated generallyby the ref- .erence numeral 21 in Figure 2, and towhich one of thehands22 of the clockmechanism is secured.

This shaft is rotated in any suitable manner but the clock is preferablyof a motor operated type embodying a suitable electric motor actuatingdevice 23, common in clocks of this character.

A shaft 24 is rotatably supported preferably by the plate 15 and avbracket 25 and is arranged parallel with the shaft 20. Secured to theshaft 24 for rotation therewith is a gear 26 with which the gear 19meshes, so that upon rotation of the gear 19, the gear 26 will berotated and with it the shaft 24.

Loosely mounted uponthe shaft 24 and preferably in close proximity tothe rear face of the plate 15 is a check carrying member or disc 27having a check seat 28 opening through the periphery thereof and thischeck carrier is provided with an integral hub portion 29 of a lengthconsiderably less than the adj aeent portion of the shaft 24, so thatthe shaft will extend beyond the hub, and secured to the shaft in anysuitable manner such as by means of a screw 30 and for rotation with theshaft is a collar 31, of a diameter substantially equal to the externaldiameter of the hub 29 and which abuts the hub.

A friction clutch device in the form of a coiled spring 32 encompassesthe hub 29, and one extremity of the coil is secured to the checkcarrier or hub 29 for rotation therewith. The coil is of such a lengththat its convolutions will extend over the collar 31 and the freeextremity 33 of flected so as to form a projecting finger, for a purposeto be hereinafter set forth.

The normal tendency of the convolutions of the spring 32 is tofrictionally grip the periphery of the hub 29 and the periphery of thecollar 31 so that upon rotation of the shaft 24 the check carrying disc27 will be rotated therewith by reason of the frictional binding actionof the convolutions of the spring 32 with the hub 29 and the collar 31.

In order to permit the shaft 24 together with the gear 26 to rotateindependently of the check carrying disc 27 the friction or bindingaction of this 'springis released, in a manner to be hereinafter setforth.

A check chute 34 is provided with a delivery outlet opening disposed inproximity to the periphery of the check carrying disc 27 7 so that whenthe check seat 28 is in register or alinement with the outlet of thechute 34, the checks or tokens 35 may be successively delivered into thecheck seat 28. The check carrier 27 is then advanced by rotating thesame so as to invert the check seat 28, at which time the check 35therein will be delivered therefrom on to a' support 36 which ispreferably inclined and the check will then roll down the support 36 tobe delivered into a check or coin receiving box 37, preferably throughan opening 38 in one wall thereof. This check receptacle 37 is heldagainst removal by means of a suitable lock 39, conthe coil is de--trolled by means of a key inserted in the keyhole or slot 40, throughthe front face of the plate 15.

A portion of one of the walls, preferably the bottom wall of the checkchute 34, is formed by a member 41 Which is pivotally mounted as at 42and is adapted to be moved in a direction to restrict a portion of thecheck chute to a size less than the diameter of the proper check ortoken 35, preferably by means of a spring 43, one end of which isanchored as at 44 to a portion 45 of the member 41, and the other end ofthe spring is anchored 'as at46 to' a stationary part of the mechanism.7 The portion 45 preferably forming the lower extremity of the member 41is offset with respect to the remaining portion of the member so as toextend over the face of the check carrier 27, and one edge of thisofiset portion 45 is adapted to engage a shoulder or stop 47 preferablyformed by a member 48 which constitutes one of the walls of the checkchute. The movable member 41 serves as a means for holding the checks 35in the chute 34 by engaging the edge of the check and forcing anotherportion of the edge of the check against the opposite wall of the checkchute, and also serves to prevent checks of an improper size frompassing through the check chute. In order therefore to permit of thedelivery of a check, from the check chute into the check seat 38 of thecheck carrier 37, to-wit: the first check upon the starting of theoperation of the mechanism, it is necessary to shift the member 41against the stress of the spring43 to open the chute to allow the checksto pass therethrough.

This is accomplished preferably by means of a pin or projection 49carried by and projecting laterally from the face of the check carrier27 and is so positioned with respect to the axisof the check carrierthat at a predetermined time in the rotation of the check carrier, itwill engage the edge or the end 'of the portion 45 of the member 41 atapproximatelythe point 50 (see Figure 3) so that upon a further rotationof the check carrier 27 in the direction of the arrow in Figure 3, themember 41 will be moved about its pivot 42 against the stress of thespring 43, thereby freeing, so to speak, the checks 35 in the checkchute 34. When one of the checks is delivered into the check seat 28 andthe member 41 held in the position to which it has been moved by the pinor projection 49, and as the check carrier advances, the remainingchecks will be held against discharge from the chuteby the engagement ofthe foremost check against the periphery of the check carrier 27.

So long as t ere are checks 35in the chute 34 the member 41 will be heldin this adjusted position against the stress of the spring 43, or in theposition shown in Figure 3, but as one position to another.

soon as the last check has passed out of the check chute the spring 43will immediately move the member 41 about its pivot in the oppositedirection so as to again restrict the size of the chute 34, or into theposition shown in Figure 2. V

The numeral 51 designates generally a spring switch of the ordinary andwell known construction which embodies a spring ac tuated member 52.adapted to be moved by means of an arm 53 into and out of position toopen and close an electric circuit embodyin g conductor members 5455secured to ter-' minal members 5657. This spring switch is of theordinary and well known construction and therefore specific descriptionthereof is not necessary, sniiiceit tosay that by the operation of thearm 53 about its pivot 58, the switch member 52 will be caused to snapfrom The arm 53 has connected to it one end ofa spring 59, and theotherend of the spring i anchored as at 60 to a stationary part of themechanism, and the spring tends normally to move the arm 53 in adirection to cause the switch element 52 to assume the position shown inFigure 2, but when the arm 53 is moved about its pivot 58 and againstthe stress of the spring 59 the switch 52 will snap to the positionshown in Figure 3.

iianual means controlled from the front of the plate 15 is provided foractuating the arm 53 in one direction to cause the switch to be renderedactive. Such means may embofy a knob or handle 61 secured to a shaft 62,and to this shaft 62 on the other side of the plate 15 is secured an armor crank 63 having a lateral projection or pin 64 which is adapted toengage one edge of the arm 53 upon rotation of the lrnob or button 61 toswing th arm 53 about its pivot 58 from the position shown in Figure 2to the position shown in Figure 3, thereby causin the switch eler out 52to snap from the position shown in Figure 2 to the position shown inFigure 3.

Tie arm 63 operates between spaced stop pins 65, which latter limit thethrow of the arm in the respective directions.

The pin 64 on the arm 63 is also adapted to on a shoulder or projection66 carried by an arm 67 that is secured to the member 41. Thisprojection or shoulder 66 is arranged within the path of movement of thepin 64 on the arm 63 so that upon the first portion of the movement ofthe 63 from the position shown in Figure 2 to the position shown inFigure 3, the arm 53 will be swung about its. pivot to move the switchelement 52 from th position shown in Figure 2, to the position shown inFigure 3. Just before the switch element 52 starts to snap from theposition shown in Figure 2 to the position shown in Figure 3, the pin 64will engage the shoulder or projection 66 on the arm 67 to draw downupon the arm and thereby swing the member 41 about its pivot 42 torelease the checks in the chute 34, so that they may be successfullydelivered into the seat 28 of the check carrier 27. As long as there areany checks in the chute 34, the member 41 will be held against returnmovement, but upon the release of the knob or button 61, the spring 59would have a tendency to return the arm 53 and thereby snap the switchelement 52 back to the position shown in Figure 2, thereby interruptingthe circuit, which is not desired. Therefore, in order to overcome thisobjection, means are provided for locking the member 41 against suchreturn movement while there are checks in the chute 34.

Any suitable locking means for the purpose may be provided, such as alocking dog or member 68 which is pivotally mounted as at 69 to a fixedor stationary portion 7 O of the mechanism. The free end 71 of thislocking dog 68 is adapted to engage over or stand within the path of thereturn movement of the portion 72 of the arm 53, and a spring 73 isprovided which engages a stationary projection 74 and a projection 75 onthe locking dog 68, and tends normally to move the end 71 of the lockingdog into a position to engage such portion of the arm 53.

A stop 76 limits the movement of the dog 68 under the influence of thespring 73. A pin or projection 77 is carried by the member 41 andengages a shoulder or projection 78 on the dog 68 so to swing thelocking dog 68 about its pivot 69 into an inactive position when themember 41 is moved to the position shown in Figure 2, under theinfluence of the spring 43. I

-As the memher41 is moved about its pivot by being drawn downwardly byreason. of the engagement of the pin 64 on the arm 63 with the shoulderor projection 66 on the arm 67, the projection 77 will move out ofcontact with the shoulder 78 of the dog 68 so to allow the spring 73 tomove the dog 68 to the position shown in Figure 3 and into the path ofthe portion 72 of the arm to be engaged by such arm, thereby lockin thelatter in the position shown in Figure 3. Upon release of the knob orbutton 61 and when there are checks in the chute 34, the member 41 willbe held against return movement and the parts will be maintained. intheir locked positions. When, however, the last check is discharged fromthe chute 34, the member 41 will then be shifted about its pivot byreason of the stress of the spring 43 causing the pin or projection 77on the member 41 to en age the shoulder o-r projection 78 on thelockingdog 68 to rock the latter about its pivot 69 against the stressof the spring 73, and thereby move the extremity 71 out of contact withthe arm 53, re leasing the latter so that it will move under the stressof the spring 59 to cause the switch element 52 to snap from theposition shown in Figure 3 to the inactive position'shown in Figure 2.

In the absence of checks in the check chute, it is desirable to-arrestthe rotation of the check carrier 27 so as not to interfere with theoperation of the clock work and as the check carrier is connected withthe clock work through the medium of the friction clutch mechanismembodying the coiled spring 32, the clutch device is rendered inactive.This is accomplished in the following manner. Carried by the portion45of the member 41 is a pin or projection 7 9 which is adapted to bepositioned in the path of movement of the extremity 33 of the coiledspring 82 when the member 4145 assumes the position shown in Figure 2,that is when there are no checks in the chute. Under these conditionsthe check carrier will continue to rotate with the shaft 24 until thepin 49 engages the edge 50 of the portion 45 of the member 41 and willswin the member 41 about its pivot 42 against the stress of the spring43. As soon, however, as the pin or projection 49 passes out of mentwith the portion 45 of the member 41, the spring 43 will immediatelyreturn the member 41 to the position shown in Figure 2 and will positiona shoulder or extension 80 carried by the p rtion 45 of the member 41 inthe path of movement of the pin 49 to be engaged by the latter (seeFigure 2) and thereby arrest the rotation of the check carrier 27. Atthe same time the pin or projection 7 9 will be moved into engagementwith th end 33 of the clutch coil spring 32 to raise said end therebyloosen or expand the coils or convolutions about the collar 31 to renderthe frictional clutch formed thereby inactive, thus permitting the shaft24 to rotate independently with respect to the check carrier 27 As soon,however, as the shoulder 80 is moved away from the pin or projection 49by the operation of the knob or button 61, the pin or projection 7 9will. also be moved away from the end 33 of the clutch coil spring 32,and the latter will be rendered active to frictionally connect the checkcarr'er 27 with the shaft 24. V

If there is a check present in the check chute at that time, the member41 will be restrained against return movement under the influence of thespring 43, should the knob 61 be released. If, however, there is nocheck in the check chute, the member 41 will immediately return to theposition shown in Fig ure 2, when the knob 61 is released.

The plate 15 is provided with a slot or opening 81 in alinement with thechute 34 so that the coins in the chute will be visible and if desired,the clock dial may be provided with an opening 82 in register with theopening 81.

The clock work may be provided with an ordinary setting mechanismpreferably embodying a shaft 83 having a knob or handle 84 and providedwith a gpar 85 secured thereto for rotation therewit and which gear 85is normally held out of contact with a companion gear by means of aspring 86. By depressing the knob or button 84 so as to move the gear 85against the stress of the spring 86 and into engagement with itscompanion gear and by then rotating the shaft 83, the hands of the clockmechanism may be set in the usual manner.
